Abstract: Solar and wind energy sources are combined into a unitary system for generating electrical energy. A solar collector collects solar rays, and these rays are focused by a parabolic mirror before being conducted through a fresnel tube to a container which minimizes thermal exchange with the exterior environment. The thermal energy of the rays within the container is converted to mechanical energy by a boiler and a steam-operated turbine. A wind collector converts air currents to mechanical energy which is selectively mechanically coupled to the mechanical energy derived from the solar collector prior to being converted to electrical energy.
